Abstract

Certain DES keys have been called weak or semiweak based upon the number of distinct round keys which they produce. For the weak keys, all 16 round keys are identical and encryption is the same as decryption. For the semiweak keys, there are only two distinct round keys but no specific weakness of the DES with these keys has been demonstrated.
